The following are a couple of recommendations for setting up a Host machine for building the Android Nougat 7.1.1_1.0.0 BSP. Some of these recommendations are not exclusive of the Nougat release and may help in other scenarios. These also apply to using Virtual Machines as Host. Installing Open JDK 8 on Ubuntu 14.04 As mentioned on the Android guide for Establishing a Build Environment (http://source.android.com/source/initializing.html) there are no available supported OpenJDK 8 packages for Ubuntu 14.04, which is the version recommended and tested on the Nougat Android BSP. An alternative is downloading the Ubuntu 15.04 Open JDK 8 packages and installing them manually, which can be done by following this procedure: Download the .deb packages for 64-bit architecture from archive.ubuntu.com: openjdk-8-jre-headless_8u45-b14-1_amd64.deb with SHA256 0f5aba8db39088283b51e00054813063173a4d8809f70033976f83e214ab56c0 http://archive.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jre-headless_8u45-b14-1_amd64.deb  openjdk-8-jre_8u45-b14-1_amd64.deb with SHA256 9ef76c4562d39432b69baf6c18f199707c5c56a5b4566847df908b7d74e15849 http://archive.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jre_8u45-b14-1_amd64.deb  openjdk-8-jdk_8u45-b14-1_amd64.deb with SHA256 6e47215cf6205aa829e6a0a64985075bd29d1f428a4006a80c9db371c2fc3c4c http://archive.ubuntu.com/ubuntu/pool/universe/o/openjdk-8/openjdk-8-jdk_8u45-b14-1_amd64.deb  Once you have downloaded these three packages and checked the checksum for them install the packages (optional) install them by running: $ sudo apt-get update $ sudo dpkg -i openjdk-8-jre-headless_8u45-b14-1_amd64.deb $ sudo dpkg -i openjdk-8-jre_8u45-b14-1_amd64.deb $ sudo dpkg -i openjdk-8-jdk_8u45-b14-1_amd64.deb ‍ ‍ ‍ ‍   Increasing SWAP to compensate for the lack of RAM Having insufficient RAM especially on the linking part of the image build may cause a number of issues that are difficult to troubleshoot. In these cases it’s good to take a look at the resource monitor to see if indeed the RAM was depleted. One way to make up for the limited RAM is using a bigger swap. Google recommends at least 16GB of RAM/swap so it’s not uncommon to create a 10GB swap when working in VM, to do this please use the following commands.    $ sudo fallocate -l 10g /mnt/10GB.swap $ sudo chmod 600 /mnt/10GB.swap $ sudo mkswap /mnt/10GB.swap $ sudo swapon /mnt/10GB.swap ‍ ‍ ‍ ‍   Increasing heap size to avoid out of memory errors It is possible to encounter an out of memory error with the recommendation “try increasing heap size witj java option ‘-Xmx<size>’. If you encounter this error or would like to proactively avoid it you may run the following commands that will increase heap size to four gigabytes and then reset the Jack Server by killing it and starting it again. With the android environment initialized: $ cd my android $ export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g" $ jack-admin kill-server && jack-admin start-server‍‍‍ ‍ ‍ ‍  Fixing Jack Servers errors due to multiple users on the Host Android Nougat uses Jack Server as mono-user by default. If this is not the case for your host you would need to choose different port numbers for each user and adjust SERVER_NB_COMPILE accordingly. You can also disable the Jack server by setting SERVER=false in your $HOME/.jack. Alternatively, you may also use the patch available on the following link to myandroid/prebuilts/sdk. It will help to fix the mono-user build restriction. When installing the jack-server, it will detect if Jack server is running in the same build machine and then generate a random ports for my build instead of using the default one. https://groups.google.com/forum/#!topic/android-building/UWhJrXH8Vig

The decommission of the git.freescale.com has caused some problems to BSPs dependent on packages stored in this repository. All contents on git.freescale.com have been moved to one of three locations: NXP · GitHub  (github.com/NXP) NXP Micro · GitHub  (github.com/NXPMicro) https://source.codeaurora.org/external/imx/   In the case of some older Android BSP this causes an error when fetching the imx-firmware packages originally stored in this repository. A workaround to this is to switch the original location to the new location. To do this we would need to manually create a build directory and initialize repo to locally load the manifest files and then make this change. Android BSP won’t require this workaround. Please note that this workaround only addresses this specific error that may show up when running the script included on the BSP release. We will be using the Oreo o8.0.0_1.0.0_ga BSP release as an example. Sources for this BSP can be found on the following link: https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/android-os-for-i-mx-applications-processors:IMXANDROID?tab=Design_Tools_Tab Documentation for this BSP can be found on the following link: https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/android-os-for-i-mx-applications-processors:IMXANDROID?tab=Documentation_Tab    1) Initialize the repo. If you have tried running the imx_android_setup.sh script the android build directory should already have been created. If this is the case, please skip to the next step. If not, please create it either by running imx_android_setup.sh or manually with the following commands (using the android setup script is preferred): $ mkdir android_build Once inside the build directory, initialize the repo and then sync it: $ repo init -u https://source.codeaurora.org/external/imx/imx-manifest.git -b imx-android-oreo -m imx-o8.0.0_1.0.0_ga.xml $ repo sync   2) Find and edit the Android Manifest. Once inside the build directory after synching, enter the repo manifests directory by executing the following command while inside the android build directory $ cd .repo/manifests  And look for the corresponding Android manifest. In this case imx-o8.0.0_1.0.0_ga.xml Open this file in any text editor (use sudo if running in a directory which requires it) In this case we’ll exemplify with nano $nano imx-o8.0.0_1.0.0_ga.xml And change the git://git.freescale.com/proprietary/  to git://github.com/NXP/ Also the path for imx-firmware so the complete line goes from: < project path = "vendor/nxp/imx-firmware" name = "imx-firmware" remote = "imx-proprietary" revision = "87ba304b9efbb2e8dbdd54af4c087584fb259535" / > ‍‍ ‍ To the following: < project path = "imx-firmware" name = "imx-firmware" remote = "imx-proprietary" revision = "87ba304b9efbb2e8dbdd54af4c087584fb259535" / > ‍‍ ‍ The manifest should look like the following. Save the file with these changes.   Now you can run the imx_android_setup.sh build script successfully. Since the repo was already synced it won’t fetch the manifests again and the change we made will persist, which will allow to find the imx-firmware package on its new location.

In order to improve the speed of compilation, VMWare Player 14.0 is installed on local hard disk, and Ubuntu 18.04 LTS is installed on a SSD with at least 500GB size and USB3.1 specification. When installing ubuntu 18.04 LTS to SSD, it should be allocated at least 350GB of disk space, because compiling this version of android requires a larger disk space. The following are detailed compilation steps: Part l Configuring Ubuntu 18.04 LTS 1. Installing Ubuntu 18.04 on VMplayer 14.0 After installation is done, root user should be set at first. # sudo passwd root Then follow these steps to configuration ubuntu 18.04 for environment of compiliation --Changing sources of ubuntu 18.04 mirror If you are Chinese users, you can do the step, which can improve your system performance. # sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak # sudo geit /etc/apt/source.list Comment I.MX customers outside China do not need to modify Ubuntu source list, or can modify it to local mirror site of Ubuntu 18.04, which can improve the speed of software upgrade.    Delet all sources and copy following lines here, Then save it and exit Changing ubuntu source deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse    Then running these 2 commands to update sources and packages    # sudo apt-get update    # sudo apt-get upgrade 2.

Downloading NXP source code for Android Q10.0.0_2.1.0    File name is imx-android-10.0.0_2.1.0.tar.gz.    Copy the file to ~/, and decompress it.    # cd ~/    # tar zxvf ./imx-android-10.0.0_2.1.0.tar.gz    Then “imx-android-10.0.0_2.1.0” directory is created at ~/, now run the command to download android source code. # source ./imx-android-10.0.0_2.1.0/imx_android_setup.sh Comment imx_android_setup.sh is a script file, which includes all steps needed by the environment of android Q10.0.0_2.1.0 BSP. If network environment is enough good, several hours later, it will be done. 2. Compiling Android Q10.0.0_2.1.0 Referring to steps in Android_User's_Guide.pdf, We summaries steps for compilation here: (1) Preparing cross-compile tool chain    In Android_User's_Guide.pdf, 2 kinds of tool chain are recommended for users. --- gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz --- gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz    Users can select one of them, and then decompress it to /opt/ directory. On how to download them or more details, see Android_User's_Guide.pdf, page 3. Here we will use gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz as tool chain. (2) Beginning to Compile Android Q10.0.0_2.1.0 BSP    Since this version of Android BSP requires high memory capacity when compiling, if the memory configuration of the virtual machine is incorrect, it is very likely to cause the compilation to fail.

This documents describes how to add the NFC support to i.MX8M mini evk running Android Pie. Hardware setup: The i.MX8M mini evk (see i.MX 8M Mini Evaluation Kit | NXP) featuring Raspberry Pi compliant connector, the OM5578/RPI PN7150 demo kit can be used to perform this porting (see NFC Development Kits for Arduino and more|NXP). However a small modification must be done because some of the signals required by PN7150 are not mapped to i.MX8M mini expansion connector pins. OM5578 IRQ signal must be mapped to Raspberry Pi connector pin #19 and OM5578 VEN signal must be mapped to Raspberry Pi connector pin #21. See below a picture of the modification: Then, the two boards can fit together as shown in the picture below: Quick start using demo image: The demo image including support for PN7150, is based on Android P9.0.0 Pie (P9.0.0_1.0.0, 4.14 kernel) i.MX software release (see i.MX Software | NXP). Related documentation can be downloaded from here: https://www.nxp.com/docs/en/supporting-information/android_p9.0.0_1.0.0-ga_docs.zip. Just flash the demo image (downloaded from here: https://www.nxp.com/lgfiles/updates/NFC/ANDROID_P9-0-0_PN7150_IMAGE_8MMEVK.zip ) following guidelines from i.MX_Android_Quick_Start document (part of Android P9.0.0_1.0.0 Documentation package mentioned above). The NFC support is then included in the device settings, as shown in below screenshot of the device: Approaching the NFC tag, provided as reference in the OM5578 demo kit, to the NFC Antenna will trigger a sound notification: Unfortunately the Android demo image doesn't embed a web browser, so it won't be automatically open when the NFC tag content (an URL to the demo kit web page) is read. Otherwise (if a web browser is installed) you could see such page opening on the device: Adding PN7150 support to imx-android-pie release: If you wish to add PN7150 support to your imx-android-pie environment, just apply the patches ( imx-p9.0.0_1.0.0-ga_pn7150_patches.tar.gz file attached) from the ${MY_ANDROID} source code root folder (refer to i.MX_Android_User_Guide document part of Android P9.0.0_1.0.0 Documentation package mentioned above).  $ patch -p1 -d device/fsl/ <device_fsl.patch  $ patch -p1 -d packages/apps/Nfc <packages_apps_Nfc.patch  $ patch -p1 -d hardware/nxp/nfc <hardware_nxp_nfc.patch  $ patch -p1 -d vendor/nxp <vendor_nxp.patch  $ patch -p1 -d vendor/nxp-opensource/kernel_imx/ <vendor_nxp-opensource_kernel_imx.patch When building, the PN7150 support will then be included to the android image, as shown in the demo image described above. Reference: This porting have been done (demo image and patches creation) following guidelines provided in AN11690_NXP-NCI_Android_Porting_Guidelines document.
